Slightly spoilerish: name of season 5 finale episode

Ok, so here is the latest from all around the web. The name of the LOST season 5 finale is . . . (and be warned, this is slightly spoilerish) "The Incident." The last time we heard of "The Incident" was in season 2, when Dr. Marvin Candle accidentally let slip that there was some sort of electromagnetic disturbance that spurred Dharma to start making people push the button every 108 minutes during one of his initiation videos. What could "The Incident" be? Perhaps something to do with Jugheard? Our Losties returning to the present? The Four-Toed Statue? Like always, we'll just have to wait to find out.
